Filed: 1921-01-13
Abstract: 182,831. Owen, E. H. Jan. 13, 1921. Regulating.-To regulate the speed' and power of two- and four-stroke engines, the normal charges are supplemented by variable additional charges supplied by pumps, the clearance in the working cylinders being adjusted in accordance with the total weight of charge admitted thereto. Fig. 2 illustrates a four-stroke engine having a pump 2 for supplying additional charges to the working cylinders 4 through the valves 3, 4<A>. The pump piston is secured by rods 6, 7 to a crank 8 geared to a shaft carrying the main crank 11. A slipper 14 secured to the rods 6, 7 slides on an arc-shaped guide 15, which is turned about the shaft 16 to vary the stroke of the pump. Mounted in the head of the cylinder 4 is a piston 26 for varying the cylinder clearance. The piston is controlled by a cam or eccentric 25 actuated through worm gearing 23, 24, the worm 23 being adjusted simultaneously with the stroke of the pump piston by a shaft 22 connected through gearing and linkage to the end 17 of the guide 15. Fig. 3 shows one of a pair of cylinders 4 and a double-acting charging pump 2 for a twostroke engine in which the piston 3 compresses and delivers to the combustion space a normal charge. When the exhaust port B is uncovered, an additional scavenging-charge is supplied from one end of the pump, a further charge being delivered from the opposite end of the pump when the exhaust port is closed. The pump stroke and the piston 26 for varying the clearance are adjusted as described with reference to Fig. 2. A modified construction of engine is described in which a normally reciprocating and adjustable piston replaces the stationary piston 26 in the cylinder head. According to further modifications, (1) the main piston slides in an outer cylindrical sleeve which is adjustable to vary the clearance, and (2) part of the cylinder charges are rejected during compression through a series uf valves opening in succession, in the cylinder head. Each of the engines according to the invention operates (1) with its normal charge only, (2) with its normal charge supplemented by one or more pump charges, or (3) with pump charges only.

Title: Process for the manufacture of fluoranthene derivatives
Filed: 1948-01-22
Abstract: 1 : 2 : 3 : 4-Tetrahydro- and 1 : 2-dihydro-fluoranthenes containing a substituted or unsubstituted amino alkyl group in the 1-position are prepared by reacting a 1 : 2 : 3 : 4-tetrahydro- or a 1 : 2-dihydro-fluoranthene or an alkyl derivative threof except a 1-alkyl derivative, having either a metal substituent in the 1-position or in the presence of a reactant capable of inserting a metal substituent in the 1-position, with an organic sulphonic ester of an alkanol which contains a disubstituted amino group, or a halogen atom, a hydroxyl group or a substituent capable of being converted to an amino group by hydrolysis or reduction.  When necessary or desired the substituent capable of being converted into a substituted or unsubstituted amino group may be so converted.  The corresponding quaternary compounds may be formed by treatment with the usual quaternating agents.  The alkyl radical of the alkanol ester may have a straight or branched chain or may form part of a ring.  The amine group may contain as substituents an aliphatic, alicyclic, araliphatic, or heterocyclic radical.  Substituents which may be converted into the amino group by hydrolysis or reduction include acylamino and nitro groups.  As organic sulphonic esters of alkanoles there are mentioned the p-toluene sulphonic acid ester of oxyethyl diethylamine, oxyethyl dibutylamine, oxyethylpiperidine, oxyethylmorpholine, oxypropyl - dimethylamine, oxypropyl - diethylamine, oxyisopropyl - dimethylamine, oxybutyl - diethylamine, oxypentyl - piperidine, dimethylaminocyclohexanol, and oxy-N-alkylpiperidines such as 3-oxy-N-methyl-piperidine or oxyacetonitrile.  The alkylation is preferably carried out in an inert solvent such as toluene, benzene, xylene, or nitrobenzene, and in the presence of an inert gas such as nitrogen.  Agents which are capable of forming metal derivatives of the hydrofluoranthenes are the alkali and alkaline earth metals and their amides, hydrides, hydrocarbon compounds and alcoholates such as sodamide, sodium hydride, lithium - butyl, potassium - phenyl, lithium - phenyl, potassium tertiary butylate and potassium tertiary amylate. Quaternating agents mentioned include alkyl and alkenyl halides, aryl sulphonic esters, dialkyl sulphates and aralkyl halides.  In an example a toluene solution of 1 : 2 : 3 : 4-tetrahydrofluoroanthene is treated first with sodamide and then with para-toluene sulphonic acid b -diethylaminoethyl ester, to give 1-(b -diethylaminoethyl)-1 : 2 : 3 : 4-tetrahydrofluoranthene.  A sample has been furnished under Sect. 2 (5) of 1 - (g  - piperidino - propyl) - 2 : 2 : 4 - trimethyl - 1 : 2 - dihydrofluoranthene made by treating a xylene solution of 2 : 2 : 4-trimethyl-1 : 2-dihydrofluoranthene first with sodamide and then with p-toluene sulphonic acid-g -acetoxypropyl-ester followed by hydrolysis with caustic alkali, treatment with thionyl chloride and finally with piperidine.

Title: Control linkage for a band type brake
IPC: F16D49/10
Filed: 1955-01-24
Abstract: 763,800. Band brake CATERPILLAR TRACTOR CO. Jan. 24, 1955 [April 30, 1954], No. 2032/55. Class 103 (1). In order to prevent any recoil from being transmitted to the brake pedal in a control linkage for a band-type brake when the brake drum of the steering clutch of a tractor changes its rotational direction an intermediate lever 14 pivoted at 16 to a fixed bracket 17 is interposed between the brake rod 13 and the stationary pivot 16. Pivoted to the lever 14 at a point 20 intermediate its ends is a floating toggle link 19  which is connected by a pin 21 to a bellcrank brake actuating lever 22. This actuating lever 22 is provided with spaced anchor pins 23 and 24 which serve as pivot means as the brakes are applied. In the fully released position of the brake illustrated in Fig. 1, the anchor pins 23, 24 are seated in their respective sockets 23a, 24a in a fixed bracket 17 and retained in this position by a return spring 25; a line drawn through the centres of the pivot-pins 20, 21 of the toggle link 19 being substantially parallel with a line drawn through the centres of the anchor pins 23, 24. On initial depression of the brake pedal 12, the position of the actuating lever 22 is shown in Fig. 2 with anchor pin 23 acting as the pivot point while pin 24 is forced from its socket to tighten the brake band about the drum. Assuming that the steering clutch brake drum is rotating in a counter-clockwise direction upon tightening of the brake band, the resulting friction will cause the band to attempt to rotate in the same direction as the brake drum and therefore, the anchor pin 23 will remain in its socket as the brake pedal is depressed further and there will be no change of pivot points. If, however, the brake drum rotates in a clockwise direction, the position will be the same as shown in Fig. 2 upon initial depression of the brake pedal, however, further application will result in the band being carried with the drum in a clockwise direction and this will pull the anchor pin 24 back into its socket and lift the other pin 23 from its socket, as shown in Fig. 3, causing an upward and slightly counter-clockwise movement of the actuating lever 22. This arrangement prevents any recoil from being transmitted to the brake pedal.

IPC: G01R27/02
Filed: 1946-01-21
Abstract: 649,574. Frequency measurements. SANGAMO WESTON, Ltd. Jan. 21, 1946, No. 2040. [Class 37] [Also in Group XXXVIII] In an electrical measuring or remote indicating device, the slider of a potentiometer forming two adjacent arms of a self-balancing bridge, is controlled by balance determining means and its position provides a measurement indication. In Fig. 1, the potentiometers 10, 11 and coil 16 of a Ferraris motor, are connected in parallel across the A.C. supply 12, 12 and the potentiometer tappings 13, 14 are connected to the second motor coil 15. The motor rotor is mechanically coupled to tapping 13 which is thereby automatically positioned to correspond with tapping 14. The motor and potentiometer 10 may be located remote from potentiometer 11. In Fig. 2, the impedances 17, 18, e.g. a resistor and capacitor, are in series across the A.C. supply 12, 12 and in parallel with the potentiometer 10 and Ferraris motor coil 16. The second motor winding 15, connects the common point of the impedances 17, 18 and the tapping 13 of potentiometer 10 coupled to the motor rotor. In this case an alteration of the supply frequency is reflected in a change in the voltage distribution across the impedances 17, 18 which causes a corresponding alteration in the current in coil 15 to produce a rotation of the motor and a corrective movement of tapping 13, the position of which may represent the frequency of the supply. If the impedances 17, 18 are of the same kind, the position of tapping 13 indicates their relative value. The circuit in Fig. 3 operates similarly to that in Fig. 2, but as a fixed frequency. The coils 20, 21 surround the iron core 22, which is movable through the coils in response to changes of the liquid level 24, being connected by the cord 26 to the flow 23 and counterbalance weight 25. A displacement of core 22 produces a differential alteration in the inductance of coils 20, 21, an unbalance current flows in coil 15 of the control motor which re-sets tapping 13 to balance, and thereby effects an indication of the liquid level change. In alternative arrangements the Ferraris motor may be replaced by a dynamometer type movement and the indicating scale expanded by gearing between the needle and the movement or by a spiral form potentiometer 10. The variable resistor 11, Fig. 1, may be replaced by two separate resistors each changeable in accordance with the controlling factor and the inductances 20, 21 in Fig. 3 may each have movable cores or only one inductance may be so adapted.

Filed: 1931-01-22
Abstract: 371,411. Preventing inductive disturbance. STANDARD TELEPHONES & CABLES, Ltd. and LATIMER, K. E., Columbia House, Aldwych, London. Jan. 22, 1931, No. 2154. Drawings to Specification. [Class 40 (iv).] In compensating unbalances in cables, each unbalance is corrected separately by the use of a " tail " comprising three or more conductors in the form of a cable, preferably spiral four tail. While this method may be used for correcting unbalances within quads, it is particularly suitable for correcting unbalances between quads, since a particular unbalance can in general be corrected without affecting any other unbalance. The exceptions to this are pair to pair and side to shield unbalances, and these are preferably corrected first therefore. It is shown how a single tail may be used to correct phantom to side, side to side and pair to pair unbalance and two tails may be used for phantom to phantom unbalance and unbalances to shield. When quads which are not adjacent are concerned, connections may be made to opposite ends of the tail. In an example, each loading section comprises eight cable lengths with cross-splicing points A, B, A, C, A, B, A, with cross-splicing between different quads only at the point C. The unbalances which remain after cross-splicing are corrected by means of tails at the points B, C. The invention may be applied to the elimination of far-end cross-talk in accordance with the method described in Specification 376,245. Specifications 239,577 and 291,511, [both in Class 40 (iv), Telephones &c.], are referred to.
